In the mid-1980s producer Giorgio Moroder released a highly controversial version of the silent movie era classic: Metropolis. According to Wikipedia:
In 1984, a new restoration and edit of the film was made by Giorgio Moroder, a music producer who specialized in pop-rock soundtracks for motion pictures. Moroder's version of the film introduced a new contemporary pop music soundtrack for the film. Although it restored a number of previously missing scenes and plot details from the original release (in particular, Moroder's version restores the character of Hel, who was omitted from the original release version of the film due to problems with American censors), his version of the film runs to only 80 minutes in length, although this is mainly due to the original intertitles being replaced with subtitles, and being run at 24 frame/s. The "Moroder version" of Metropolis sparked heated debate among film buffs and fans, with outspoken critics and supporters of the film falling into equal camps.
The Moroder film's release came at the same time that Queen released their video "Radio Ga Ga", which featured footage of the film. Though the Moroder version was nominated at The 1985 Razzie Awards for Worst Original Score and Worst Original Song (with Freddie Mercury), it brought the film back to the public eye.
Copyright laws have been resolved and the Moroder version has now been released onto DVD and Blu-Ray.
